A core that loads the first of several names (yabause: saturn_bios.bin,
sega_101.bin, mpr-17933.bin) needs one of them. Profiles wrote this as
required on the first name and optional on the others, so verify and
the gap report called saturn_bios.bin a missing required file while
sega_101.bin was held, and a set held only through a name marked
optional read as a need met by an optional file.
Model: an explicit group on the file entry, mirroring the platform
field. priority was not reused: it is a rank, read by slot.py, region.py
and truth.py inside a (system, region) slot, and that slot is not the
set. px68k-sdl ranks its IPL list and its font list each from 1 in one
system, pom2 ranks one list per machine model, DuckStation ranks 105
images across every region and takes any of them. A rank cannot say
where one list ends. priority stays the order inside a group.
Readers, through alternatives.settle_sets:
- verify --emulator and the emulator pack: a held member fills the
set, the others leave the report, a set nobody holds is one gap
under its first member naming the others.
- find_undeclared_files (verify platform, core complement of packs and
manifests): same rule, a platform declaration or launcher counts as
answering the set.
- cross_reference: excused members are set aside as other versions.
- slot.py: ranks compare members of one set only.
- archive members: a required set inside an archive is met by one.
- truth: a member gives no requirement of its own, one_of and
one_of_required carry the set, and the exporters and the diff leave
such a line's required as the platform wrote it.
- validate_schemas: members of a group share required.
Both formats write every accepted md5 when the truth extends the platform's list without contradicting it, but only Batocera answered written_list, so landed_changes reported nothing for a diff the maintainer would find. Both now name the list they write when it holds several values.
An element's mandatory flag came from the one truth entry its md5 paired
with. saturn/saturn_bios.bin names yabause, yabasanshiro and kronos,
which require it, and was paired with the beetle_saturn entry, which
does not. Each named core's entries for the file, found by name, now
decide, except a namesake elsewhere in the same tree (bluemsx KANJI.rom
under Shared Roms is not the one under MSX2+ - European).
An element whose md5 the truth contradicts without naming another is
written back whole. It was counted as an entry the format cannot keep.
It now counts as kept, and the md5 it keeps is named as withheld.
An element lists its cores. Its mandatory flag now follows whether those
cores need the file, and stays as written where none of them reads it.
cdi/cdibios.zip keeps mandatory=false (same_cdi does not read it), the
two amiberry kickstarts keep theirs, saturn_bios.bin becomes optional
for the three HLE cores it names.
A changed element was rendered again, losing its alignment and the
place of its attributes, and an element whose md5 list was only
reordered (neogeo.zip, the same 24 digests) was rewritten too: Recalbox
accepts any digest of the list (Bios.cpp:109-130), so the order is not
content. A changed attribute is now replaced where it stands, one
dropped goes with its space, one added goes before />, and each system's
opening tag keeps its own indentation. An empty truth gives back the
cached es_bios.xml byte for byte.
The attribute pattern took letters only, so md5 never entered the comparison and an element whose digest the truth corrects kept Recalbox's text. A test written before the change caught it. The RetroDECK fixture now names the core that reads its addition, as the placement rule requires.
Every <bios> element the model held was rendered again, so attribute order, alignment, a line break inside md5 and the case of a digest changed in 222 elements that stated the same thing. The diff deleted 451 lines for 136 corrections. An element whose attributes say what Recalbox wrote now keeps Recalbox's own text: 175 lines, the corrections.
Profiles, the wiki, comments, docstrings, command output and schema descriptions carried em-dashes, clause-joining semicolons, unicode arrows, box-drawing banners and check-mark glyphs. Each sentence was rewritten rather than having its character swapped. Hashes, paths, source_ref values and every cited file:line are unchanged, which a comparison of each parsed profile against the previous revision confirms.
validate_pr comments now say PASS and FAIL in words, and source_ref values in a profile's structured blocks render as code. test_prose_style fails if any of these comes back, in tracked files or in the generated site.
RomM kept hashes the truth contradicts beside the corrected one, RetroDECK kept a cleared md5, Recalbox counted changes on an element it writes back whole, and two record formats counted fills no record could hold.
Run ruff check --fix: remove unused imports (F401), fix f-strings
without placeholders (F541), remove unused variables (F841), fix
duplicate dict key (F601).
Run isort --profile black: normalize import ordering across all files.
Run ruff format: apply consistent formatting (black-compatible) to
all 58 Python files.
3 intentional E402 remain (imports after require_yaml() must execute
after yaml is available).
